In-vivo measurements of wear over a five-year period showed belleGlass to average only a little over 1.2 microns a year – closer to the wear rate of natural teeth than any other material tested.

belleGlass NG Opaceous Dentin more closely matches the coefficient of thermal expansion (CTE) of natural dentin. This means belleGlass NG will look and act virtually the same as the natural tooth structure.

Typical wear to natural dentin in occlusion with porcelain restorations. Porcelain is five times harder than belleGlass NG (per Vickers Hardness Rating – composites score 60 to 175 and porcelain scores 600 to 700).
